ABSTRACT

The invention is a method to inspect multiple conditions of an auto feeding device feeding standard inspection papers into a scanning device while the said auto feeding device in QC process. The method is to use a bar code printed on the standard inspection paper to recognize the conditions that feeding multiple papers in one time, paper jam, paper inclined, etc. The bar code is continuous and unique, and therefore, the results for which standard inspection paper happened problem and how many more papers needing to be inspected are known immediately.

1. FIELD OF THE INVENTION

[0001] The present invention relates to a document inspection method forauto feeding device, especially focusing on the QC process of autofeeding device to inspect the variable conditions of paper feedingmotions.

2. BACKGROUND OF THE INVENTION

[0002] The world is going better and better, thus the first priority foreverything is efficiency, economization and precision. On the otherhand, when the worldwide economy goes down and it is happened all thetime, labor fee is the huge fixed outgoing for any company monthly.Therefore, no matter hardware or software is created to be instead ofhuman resource for decreasing the fixed outgoing. Moreover, those highlyintellective products, hardware and software, can work continuouslywithout rest, emotion and mistake, and this is the object what thepresent world needs. The invention is created based on the abovesituation.

[0003] Up to now, there are many detail procedures in QC process thatneed to be inspected by human being in companies, because some detailprocedures cannot be executed by hardware. In the producing field ofscanning devices, such as scanner and the accessory products, are stillinspected in QC process by labor. For instance, the auto feeding device,which is checked by a man to watch the conditions of papers feeding intoscanning device through auto feeding device. Many conditions for that,such as multiple papers in one feeding process, paper jam, paperinclined, etc. Thus, the process for a man to watch is very important,otherwise, product quality and reputation are affected, further, thecost for post services is double or even more, and the result is almostnot compensated.

SUMMARY OF THE INVENTION

[0004] The major object of the present invention is to use the bar codeprinted on standard inspection paper for identifying the paper feedingcondition, which is a single one or multiple papers. The bar codes onthe standard inspection papers are continuous, thus, in case of the barcodes are not continuous, it means that the condition, multiple papersare fed in one time, was happened.

[0005] The second object of the present invention is to use the bar codeprinted on standard inspection paper to identify the paper jam is takenplace or not. The bar codes on the standard inspection papers arecontinuous, thus, in case of the bar codes are not continuous, it meansthat the condition, paper jam, is happened.

[0006] The third object of the present invention is to use the bar codeprinted on standard inspection paper to identify the layout of the paperfed into scanner is inclined or not. The position of the bar code on thestandard inspection paper is same as each one, therefore, a scannedimage is recorded after scanning, and the recorded image is comparedwith standard position file, the condition, inclined paper, isrecognized after comparing.

[0007] The fourth object of the present invention is to use the bar codeprinted on standard inspection paper to know which paper the problem is.The bar codes are continuous, for example, numerical combination, and incase of problem happened, the problem paper is known soon.

[0008] The fifth object of the present invention is to use the bar codeprinted on standard inspection paper to count how many pieces of papersare fed into scanner for inspecting auto feeding device. A QC standardis formulated, and it means a certain amount of papers are fed intoscanner by auto feeding device without problems, the inspectedauto-feeding device is passed. Also, the inspection is stop immediatelyand next one is started inspecting. Thus, standard inspection papers arenot consumed and the inspecting schedule is precisely controlled.

[0009] To describe more clearly about a structure improvement ofadjustable interval of a display frame of the present invention, adetailed explanation in accordance with several diagrams are asfollowing:

BRIEF DESCRIPTION OF THE DRAWINGS

[0010]FIG. 1 is the standard inspection paper of the present invention.

[0011]FIG. 2 is the auto-feeding device of the prior art.

[0012]FIG. 3 is the inspection flow of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The present invention is a document inspection method for autofeeding device, and it uses a pattern printed on a standard inspectionpaper with the feature of uniqueness and continuous. Generally speaking,the pattern takes the type of bar code. When scanning, a reading unit inscanning device reads an image of a bar code and records the image to arecording device, thus, the image is compared with a standard image inthe recording device or a computer to recognize the functions of paperfeeding, paper positioning, etc. for a auto feeding device.

[0014] Please refer to FIG. 1, which is the standard inspection paper ofthe present invention. Wherein, there are at least two identical barcodes 6 on standard inspection paper 1, and the two bar codes 6 aredistributed symmetrically on the top of the standard inspection paper 1.When the standard inspection paper 1 feeding into a scanner forinspection scanning, the two bar codes 6 are the first priority to bescanned for inspection. Bar code 6 represents two meanings: the first isthat it is with the feature of uniqueness, and the first feature helpsto immediately recognize what the problem is happened within the processof the standard inspection paper 1 feeding into scanner via auto feedingdevice; for a preferred embodiment, the bar code is a serial number,which not only represents the special standard inspection paper witheach serial number, but also the count function because the serialnumber is continuous; the second, the bar codes 6 are on fixed positionsof the standard inspection paper 1, thus, the situation that thestandard inspection paper 1 is inclined or not is known after laying outthe standard inspection paper 1 on scanner.

[0015] Please refer to FIG. 2 and FIG. 3, which are the auto-feedingdevice of the prior art and the inspection flow of the presentinvention. For further understanding, please take FIG. 2 and FIG. 3 asreferences. The following is the steps of the invention:

[0016] step 1: having auto feeding device 3 on a working position ofscanning device 2, and starting the auto feeding device 3;

[0017] step 2: a state of auto feeding is starting, which means the autofeeding device 3 feeds the standard inspection paper 1 with bar codes 6to a working position of scanner 2;

[0018] step 3: the scanner 2 scans the standard inspection paper 1;

[0019] step 4: a reading unit 4 in the scanner 2 reads the bar codes 6on the standard inspection paper 1, and a recording device 5 records theconditions while the bar codes 6 are scanned by scanner 2; the happenedconditions may be any of the following: the first, multiple standardinspection papers 1 are fed into scanner 2 in one time, because autofeeding device 3 cannot grab a piece of paper or sticking force ofpapers is too tight, thus the different bar codes 6 on different papersare not continuous and it means that problem is happened; the second,standard inspection paper 1 is jammed somewhere between scanner 2 andauto feeding device 3, and even the reading unit 4 is driven to read barcodes 6, it is possible that the images of bar codes 6 are notcompletely caught up or missed; the third, in case of not fully readingthe images or wholly missing the images, therefore standard inspectionpaper 1 is probably inclined when laying out on scanner 2; the fourth, anumber, the happened problem paper number, is variable because problemhappened randomly, thus any paper happened problem can be knownimmediately;

[0020] step 5: the inspection for the single standard inspection paperis finished, if there are still some standard inspection papers in autofeeding device 3, then going back to step 2, otherwise, going to nextstep;

[0021] step 6: the whole process is done.

[0022] As a conclusion of the above mention, the present invention onlyuses bar codes printed on standard inspection paper to inspect variableconditions when auto feeding device in QC process. Comparing with theinspection of human resource in prior art, the present invention trulyovercomes that and totally conforms to the spirits of invention.

[0023] However, the above-mentioned statement is only a preferableembodiment of the present invention and cannot be taken as therestrictive scope of the present invention. All the variation andamendment from the claims of this patent application of the presentinvention will possess the meaning of the present invention and will bewithin the spirit and field of the present invention, so they will beviewed as the situation of further execution of the present invention.
